Part A

Write a Java program that reads an integer n from the keyboard and loops until 13 n 13 is successfully entered. A do-while loop is advised.

Part B

Write a Java program that reads an integer n from the keyboard and prints the corresponding value n!. [This is n factorial]. You must verify that the input integer satisfies the constraint 0 n 13; keep looping until the constraint is satisfied.

Will give thumbs up to best answer.
